Hôtel du Plessis-Guénégaud

The Hôtel du Plessis-Guénégaud (French pronunciation: [otɛl dy plɛsi ɡeneɡo]) was a French aristocratic townhouse (hôtel particulier), built 1630–1632 for the financier Louis Le Barbier [fr] to the designs of architect Clément Métezeau.

[3] It became the property of the state during the French Revolution but in 1818 was returned to its former owners, who demolished it in 1843.

The property was acquired by the École des Beaux-Arts in 1858, and Félix Duban began construction of the Bâtiment des Expositions, which was completed in 1862.

[4] In 1660, Anne-Marie Martinozzi, Princesse de Conti, who was a niece of Cardinal Mazarin, acquired the hôtel, which then became known as the Hôtel de Conti.

In 1670 she exchanged this hôtel, as well as her beautiful country house in Bouchet, for the Hôtel de Guénégaud on the Quai de Nevers, only a short distance upstream.
